Liquid Film Behaviors of Oscillating Slug Flows
Liquid film thickness is an important parameter for predicting boiling and condensation heat transfer coefficients
in two-phase slug flow. In the present study, liquid film thickness of oscillating slug flow in a capillary tube is
experimentally investigated. Circular tube with inner diameter of 1 mm is used for the test tube, and water and ethanol are
used as working fluids. The laser focus displacement meter (LFDM) is used to measure the initial liquid film thickness.
